  ],
  "summary": "Consensus failure in github.com/btcsuite/btcd",
  "details": "The btcd Bitcoin client (versions 0.10 to 0.24) did not correctly re-implement Bitcoin Core's 'FindAndDelete()' functionality, causing discrepancies in the validation of Bitcoin blocks. This can lead to a chain split (accepting an invalid block) or Denial of Service (DoS) attacks (rejecting a valid block). An attacker can trigger this vulnerability by constructing a 'standard' Bitcoin transaction that exhibits different behaviors in 'FindAndDelete()' and 'removeOpcodeByData()'.",
